What Is 5w30 Engine Oil?

5w30 engine oil is one of the most commonly used oils in petrol and diesel car engines, SUVs and vans. Designed to perform across a wide range of temperatures, the low viscosity of 5w30 oil means it efficiently travels around the engine, even in the cold.

The ‘5w’ of 5w30 refers to how the oil behaves in cold conditions. The ‘w’ stands for winter – so the lower the number, the better it flows in low temperatures. The ‘30’ refers to the oil’s viscosity at high operating temperatures. This combination helps your engine start quickly and easily in the cold and keeps your engine protected once you’re driving.

How Often Should I Change My 5w30 Engine Oil?

How often you change your oil will depend on your vehicle’s age and your driving conditions. If you’re using fully synthetic 5w30 engine oil, we recommend changing it every 6,000 miles or every six months. For more guidance, check your owner’s manual for your specific manufacturer’s recommendation.

How Can I Tell When I Need To Change My Engine Oil?

There’ll be a few signs that you need to change your engine oil, like a dashboard oil warning light, knocking or clicking engine noises and smoke from your exhaust. Also, when checking your oil levels, if you notice the oil on the dipstick is dark, thick or gritty, it’s time to change your engine oil.

FAQs

Does It Matter Which 5w30 Oil I Use?

As with any oil, it’s important to check the exact specifications of your vehicle in the owner's manual. Diesel and petrol cars might require different types of oil depending on your model.

What Is The Difference Between 5w30 And 5w40 Engine Oil?

The main difference between 5w30 and 5w40 oil is their viscosity at operating temperatures. Both oils behave the same way in cold conditions as they are both ‘5w’. Where they differ is at high temperatures, as the ‘40’ in 5w40 means that the oil stays thicker whilst driving.

What Does ‘Fully Synthetic’ Mean?

Fully synthetic engine oils are entirely man-made, rather than refined from crude oil like other engine oils. Many manufacturers today insist on using fully synthetic oil as it has been specifically engineered for consistency and performance, helping your engine to work at its best.

How Long Does An Open Container Of 5w30 Engine Oil Last?

An open container of 5w30 engine oil can last anywhere from 1-2 years, but you should always check the use-by date on the packaging first. We recommend keeping your engine oil somewhere cool, dry and away from direct sunlight to avoid degrading the oil’s quality.
